Abstract

Chemical analysis of fog water collected by impaction in a pre-cooled chamber in Delhi has shown high concentrations of major ions. The dominant ions measured were Na** plus , K** plus , Ca** plus **2, and Mg** plus **2. The concentrations of acidic ions, SO//4** minus **2 and NO//3** minus , were low. The pH values in the fog water were highly alkaline and varied from 6. 4 to 7. 6. The high concentrations of soil-oriented components, especially Ca** plus **2, were more than sufficient to neutralize the small acidity in the fog water and were responsible for maintaining high alkaline pH. The pH values of fog water did not attain the low values in India (Delhi), as found in other polluted environments of Europe and the northeast United States.
